Solubility

This type of mixture contains two or more substances that are visibly distinguishable. 

• homogeneous
• heterogeneous
• solution
• colloid

If an electrical current can run through a solution, it is said to contain

• magic
• nonelectrolytes
• electricity
• electrolytes

Which of the following is an electrolyte?

• sodium chloride
• sugar
• water
• sand

Solutions in which electric currents cannot run through are said to be

• noncolloidal
• electrolytes
• nonelectrolytes
• conductors

An example of a nonelectrolyte is

• sugar water
• salt water
• sodium chloride
• hydrogen chloride

A solute that contains polar molecules will dissolve in a solvent that contains

• nonpolar molecules
• polar molecules
• covalent molecules
• equal-sized molecules

The rule that refers to polar molecules dissolving polar and nonpolar dissolving nonpolar is 

• this dissolves that
• like dissolves like
• same dissolves same
• here dissolves there

The "like dissolves like" rule is the reason why water cannot dissolve

• salt
• sugar
• vinegar
• oil

This substance is considered a polar substance

• water
• oil
• butter
• gasoline

Molarity is measured in

• mols per kg
• mols per L
• mols per kJ
• mols per mL
